Analog buys Linear

Too bad. The cultures were usefully different. Everybody archive their LTspice installers!

as far as I can read 11 something billion in cash the rest in ADI stock

-Lasse

Yes, $14.8 Billion, about as much as Analog is worth apparently.

Some here have mentioned they love LT because they nearly never obsolete a device. If your quantities are large enough they will always run a batch on their fabs which don't need to be anything like state of the art. I wonder if this will change. ADI obsoletes parts like everyone else.

That's for sure. You'll recall my observation that Analog's Spice model group was under a MARKETING VP :-( ...Jim Thompson

I'm looking for work... see my website.

This thing looks fairly new to ADI:

so there is a conflict with LT Spice.

And I expect a price increase.

From LT? Not possible.

This is one merger that I don't see, though. As others have said, the cultures and even customer set are very different.

The product lines, however, have a lot of overlap. At first this fact will be glowingly described as "synergy," but eventually the applicable buzzword will be "redundancy."

It wasn't hard to spin the earlier Hittite acquisition as good news, because, well, Hittite. But I don't see any upside for customers in this acquisition. I see a lot of parts going away.

Yes, a lot of overlap. More even than TI and National, at the time. OTOH, the TI and "National" groups seem to have even more overlap now.

"Good for customers" is certainly goodness but it's certainly not a requirement in a merger/acquisition. Of course, I can't see the books but I wonder how it's good for either ADI or LT.

I hope that LT folks could convince ADI to release ADICE to the public, but I think that is unlikely to happen. In my opinion the only losers due to doing that would be other SPICE vendors, but that is just my opinion.

On the bright side, it would be nice if AD produced better models, like LT's.

How many gigabucks of value did LT Spice add to the purchase price?

"Bright side"?

Unfortunately MANY of LT's models won't run on any simulator other than LTspice.

I'll grant you that many of the "little guy" companies use LTspice, but most companies of any substantial size use Cadence Tools or OrCAD PSpice (which is also owned by Cadence), or Microcap or TopSpice or...

The funny thing is... as I've pursued many model complaints about Analog Device's models not working on LTspice... they run just ducky elsewhere.

I've managed to "dumb-down" some ADI models to get them to run on LTspice but often I find insurmountable convergence issues with LTspice and abandon the effort... no one is paying me for them >:-} ...Jim Thompson

"Forewarned is forearmed." Thank you Phil.

FWIW, it's one of my habits to always archive important items on my own servers. My LTSpice archive, for instance, now includes:

LTSpiceIV.exe dated 20160622 LTSpiceIV.exe dated 20111106 LTSpiceIII.exe dated 20070723

Phil,

Don't know much about LT models or those from ADI but i know they are all hidden.

LTSpice has a advanced engine, LT has released LTSpice "freely" long time ago and after years even TI nor ADi can not compete with such a graticiel.

ADI has focused on NI infrastructure and i suspect ADI analog models are macromodels ... :-(

Different scientific culture and different business targets ... LT --> electronics lunatics ADi --> Physicists are using electronics (NI modules), from time to time.

Habib.

What's an NI model?

Not the ones they use internally for product development. that seems to be the key to LTC's models running so well--they use some variant of LTspice internally, so the models are the real deal.

LT customer support is amazing if your a small business. They will engineer a circuit design for you with no strings attached, at no charge. They have a set of experienced regional engineers that are not attached to marketing.

I sent them a sketch for a 100 Watt class D amp. It came back fleshed out and verified. My crude output filter was replaced with someting amazing. The bar for obtaining this service was set low. Three weeks later their guy was still following up.

Thus LT Spice exists for yet another reason.

My treatment from AD Tech Support as never approached the skill level exhibited by LT.
